Method, Device, and System of Resource Configuration

ABSTRACT

A method and a communications system are provided. The system includes a base station and a RNC. The base station does not report the RNC whether the base station supports an E-DPCCH power boost capability. The RNC is also informed whether a UE supports and E-DPCCH power boost capability. If the UE supports E-DPCCH power boost function, the RCE designates by default that the base station also supports the E-DPCCH power boost function even though the base station does not report whether it supports or not, and configures resources for the base station to perform channel estimation by using the E-DPCCH power boost feature for the UE. Through the solution of the system, the accuracy of channel estimation can be improved and thus a bit error rate in high-speed data transmission can be reduced.

FIELD OF THE INVENTION

The present invention relates to the field of mobile communicationstechnologies, and more particularly to a method, device and system ofresource configuration.

BACKGROUND

In the field of mobile communications, with the development of variousservices, users have higher requirements on the data transmission speed.In order to support higher speed data service, lower delay, higherthroughput and higher spectrum utilization, two new technologies areproposed, that is, High Speed Downlink Packet Access (HSDPA) and HighSpeed Uplink Packet Access (HSUPA) technologies.

New physical channels are introduced into the HSUPA technology. The newphysical channels include an Enhanced Dedicated Channel (E-DCH)Dedicated Physical Data Channel (E-DPDCH) for bearing uplink datainformation of the E-DCH and an E-DCH Dedicated Physical Control Channel(E-DPCCH) for bearing uplink signaling information of the E-DCH.

Before the new physical channels are introduced, due to the higher dataspeed and larger data blocks for transmitting data, the performance ofthe channel estimation performed according to a Dedicated PhysicalControl Channel (DPCCH) becomes worse, and cannot meet the performancerequirements for high-speed data transmission demodulation. The problemsare caused by the following reasons. In order to optimize theperformance of the uplink high-speed transmission, it is necessary tocontrol the power difference between the E-DPCCH and the DPCCH in acertain range; to ensure that the power difference is controlled in therange, it is necessary to increase the power of the DPCCH and toincrease the DPCCH signal-to-interference ratio (SIR). However, theprocess of an out loop power control (OLPC) for adjusting thesignal-to-interference ratio target (SIRtar) is slow. If the SIR isadjusted too fast, the OLPC cannot meet the requirement of the SIRchange. Therefore, the following problem may occur: when a large SIR isrequired at a high speed, the SIRtar is still a low value. At this time,the bit error rate at the high speed is significantly increased, and thethroughput is severely influenced.

Therefore, after the E-DPCCH is introduced, in order to improve theaccuracy of channel estimation, the E-DPCCH is added into the channelestimation. When the E-DPCCH is added into the channel estimation,through the power boost characteristic of the E-DPCCH, the powerdifference between the E-DPCCH and the DPCCH can be controlled in arange allowed by the performance, and at the same time, the requirementfor the signal-to-interference ratio at power change is met. In thisway, the accuracy of the channel estimation is improved significantly.

However, in the prior art, a radio network controller (RNC) cannotallocate E-DPCCH power boost resources to a radio link (RL) of a UEhaving the E-DPCCH power boost capability when performing resourceconfiguration. As a result, even when the UE has the E-DPCCH power boostcapability, the UE cannot perform the channel estimation by using thepower boost characteristic of the E-DPCCH. Therefore, the problems ofinaccurate channel estimation and lower data demodulation performancestill occur during high-speed data transmission.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the technical solutions, objectives and merits of the presentinvention clearer, the present invention is described in detail withreference to the accompanying drawings in the following.

In the following embodiments, a Wideband Code Division Multiple Access(WCDMA) system is taken as an example of a radio communication system.However, the present invention can be widely used in other radiocommunication systems, for example, a Long Term Evolution (LTE) system.The RNC, Node B, and UE have different names in other radiocommunication systems, which, however, are also applicable to thetechnical solutions provided by the embodiments of the presentinvention.

When a Radio Resource Control (RRC) connection is set up between a UEand an RNC, the UE reports whether the UE has the E-DPCCH power boostcapability to the RNC through an RRC Connection Request message or anRRC Connection Setup Complete message. However, when the RNC and theNode B synchronize the configuration and the capability information ofthe Node B, the Node B may not report whether the Node B has the E-DPCCHpower boost capability actively. Therefore, the RNC cannot acquirecorrectly the capability information of the Node B, and cannot correctlyconfigure the radio resources.

For example, the RNC may consider that the Node B does not have theE-DPCCH power boost capability by default if the Node B does not reportto have the capability, so when performing radio link (RL) configurationor RL re-configuration, the RNC does not notify the Node B to allocateE-DPCCH power boost resources to the RL of the current UE. That is, theNode B does not configure to perform the channel estimation by using theE-DPCCH power boost characteristic for the UE. In this case, even if theUE has the E-DPCCH power boost capability, the E-DPCCH power boostcharacteristic cannot be used, and the UE and the Node B still performthe channel estimation by using the DPCCH, resulting in the problem oflow accuracy of the channel estimation and a high bit error rate inhigh-speed data transmission.

Therefore, to configure optimal radio resources for the Node B and theUE, it is required to clearly inform the RNC whether the Node B has theE-DPCCH power boost capability.

FIG. 1 shows a resource configuration method according to a firstembodiment of the present invention. As shown in FIG. 1, the methodincludes the following steps:

Step 101: Acquire capability information of a Node B, in which thecapability information includes information indicating whether the NodeB has an E-DPCCH power boost capability.

Step 102: Acquire capability information of a UE, in which thecapability information includes information indicating whether the UEhas the E-DPCCH power boost capability.

Step 103: When the UE and the Node B both have the E-DPCCH Power boostcapability, notify the Node B to configure resources for performingchannel estimation by using the channel power boost capability for theUE.

The implementation of the steps in this embodiment is described indetail in the following.

In this embodiment, an RNC acquires the capability information of theNode B and the capability information of the UE, and according to theacquired capability information, optimal resources of the Node B forchannel estimation are configured for the current UE, so that when theUE and the Node B both have the channel power boost capability, the NodeB can perform the channel estimation by using the channel power boostcapability. Therefore, the accuracy of the channel estimation isimproved, and the bit error rate in high-speed data transmission isreduced.

Next, a second embodiment of the present invention is described indetail with reference to FIG. 2. The second embodiment also provides aresource configuration method, which includes the following steps:

Step 201: An RNC and a Node B synchronize configuration and capabilityinformation of the Node B.

In step 201, the RNC synchronizes the configuration and the capabilityinformation of the Node B through an Audit procedure or a ResourceStatus Indication procedure, or through a combination thereof.

When the RNC and the Node B implement the synchronization of theconfiguration and the capability information of the Node B through theAudit procedure, the RNC sends a Resource Audit Request to the Node B tostart the Audit procedure. During this procedure, the RNC acquires theconfiguration and the capability information of the Node B through anAudit Response message sent by the Node B. Through this procedure, theRNC may complete the synchronization of the configuration and a logicresource state of the Node B.

In order to enable the RNC to be clearly informed whether the Node B hasthe E-DPCCH power boost capability, the Node B carries an informationelement (IE) for indicating that the Node B has or does not have theE-DPCCH power boost capability in the Audit Response message.

Therefore, the RNC can be clearly informed whether the Node B can usethe E-DPCCH power boost characteristic according to the IE indicatingwhether the Node B has the E-DPCCH power boost capability carried in theAudit Response message.

The Audit procedure can be triggered under many conditions, and is notnecessarily triggered just before the subsequent steps. For example,when the RNC is started or switched, or the cell status changes, the RNCinitiates the Audit procedure.

If the RNC implements, with the Node B, the synchronization of theconfiguration and the capability information of the Node B through theResource Status Indication procedure, the RNC receives a Resource StatusIndication message sent by the Node B, and according to the message,completes the synchronization of the configuration and the capabilityinformation of the Node B. The Resource State Indication message carriesa plurality of IEs for indicating the configuration and a logic resourcestate of the Node B, including an IE for indicating whether the Node Bhas the E-DPCCH power boost capability.

The RNC can be clearly informed whether the Node B can perform thechannel estimation by using the E-DPCCH power boost characteristicaccording to the IE indicating whether the Node B has the E-DPCCH powerboost capability carried in the Resource Status Indication message.

The Resource Status Indication message sent to the RNC by the Node B canbe triggered under many conditions, and is not necessarily triggeredjust before the subsequent steps. For example, the conditions such asincreasing local cells of the Node B, deleting local cells of the NodeB, and changes of the capability of the local cells may trigger the NodeB to send the Resource Status Indication message to the RNC.

The Audit procedure and Resource Status Indication procedure can makethe RNC be clearly informed whether the Node B has the E-DPCCH powerboost capability. Furthermore, the combination of the Audit procedureand Resource Status Indication procedure can also complete thesynchronization process in which the RNC acquires the capabilityinformation of the Node B. As the triggering conditions of the Auditprocedure and the Resource Status Indication procedure are different,the sequence of triggering the two processes may be exchanged, and thetrigger of the two processes is not mutually exclusive; instead, the twoprocedures can be combined together. In this way, it is morecomprehensively ensured that the RNC accurately knows whether the Node Bcan perform the channel estimation by using the E-DPCCH power boostcharacteristic when the UE initiates the RRC connection setup.Therefore, the accuracy of the channel estimation of the UE and the NodeB is ensured, and the bit error rate in high-speed data transmissionbetween the UE and the Node B is reduced.

Step 202: The RNC receives a message sent by the UE, and is informed ofthe capability of the UE.

When the UE initiates the RRC connection, the UE starts the RRCconnection setup process by sending an RRC Connection Request message tothe RNC. The RRC Connection Request message may carry a part of thecapability of the UE. The RRC Connection Setup Complete message sent tothe RNC by the UE carries the complete capability of the UE that is notcarried in the RRC Connection Request message. By receiving the twomessages, the RNC is informed of the complete capability of the UE.

The RNC acquires the complete capability of the UE through the twomessages, and the capability includes whether the UE has the E-DPCCHpower boost capability. Therefore, the RNC is clearly informed whetherthe UE has the E-DPCCH power boost capability through the RRC connectionsetup process.

It can be seen that, step 201 may be performed before or after step 202.

Step 203: The RNC configures the resources of the Node B for the UEaccording to the capability of the UE.

After the RNC receives the RRC Connection Request message sent by theUE, the RNC notifies the Node B to configure the resources of the Node Bfor the UE according to a part of the capability of the UE carried inthe message, that is, the setup of a radio link (RL). Moreover, afterthe RNC receives the RRC Connection Setup Complete message sent by theUE and is informed of the complete capability of the UE, the RNCre-notifies the Node B to re-configure the resources of the Node Baccording to the complete capability of the UE, that is, the RLre-configuration.

Through step 201, the RNC is clearly informed whether the Node B has theE-DPCCH power boost capability, and through step 202, the RNC is clearlyinformed whether the UE has the E-DPCCH power boost capability.Therefore, in step 203, the RNC configures the resources of the Node Boptimally for the UE through the RL setup and RL re-configurationprocesses. For example, when the Node B and the UE both have the E-DPCCHpower boost capability, through the RL setup process and the RLre-configuration process, the RNC notifies the Node B to perform theresource configuration, so that the UE uses the E-DPCCH power boostcharacteristic to perform channel estimation, so as to improve theaccuracy of the channel estimation.

Through the solution of this embodiment, the RNC is clearly informedwhether the Node B has the E-DPCCH power boost capability, so as toconfigure the Node B to perform the channel estimation by using theE-DPCCH power boost characteristic for the UE when the UE and the Node Bboth have the E-DPCCH power boost capability. According to thisembodiment, when the RNC configures the Node B to perform the channelestimation by using the E-DPCCH power boost characteristic, the accuracyof the channel estimation of the UE and the Node B is improved.Therefore, the correct rate of the high-speed data transmission betweenthe UE and the Node B is ensured, and the throughput is improved.

Moreover, after the RNC configures the resources of the Node B, it canfurther configure the resources for the UE, for example, configure theresources for the UE through a radio bearer (RB) setup process or an RBre-configuration process, so that the resource configuration of the UEis consistent with that of the Node B.

A third embodiment of the present invention is described in detail withreference to FIG. 3. The third embodiment of the present inventionprovides a resource configuration method during movement of a UE, whichincludes the following steps:

Step 301: A drift RNC (DRNC) and a Node B synchronize configuration andcapability information of the Node B.

The DRNC synchronizes the configuration and the capability informationof the Node B with the Node B through an Audit procedure or a ResourceStatus Indication procedure, or through a combination thereof, so thatthe DRNC is informed whether the Node B has the E-DPCCH power boostcapability, and the specific implementation is as described in step 201in the second embodiment of the present invention.

Step 302: A serving RNC (SRNC) receives a message sent by the UE, and isinformed of capability of the UE.

The UE reports its complete capability to the SRNC through an RRCconnection setup process. Accordingly, the SRNC is clearly informedwhether the UE has the E-DPCCH power boost capability. The specificimplementation is as described in step 202 in the second embodiment ofthe present invention.

Step 303: The SRNC acquires the capability information of the Node B.

The DRNC forwards the capability information of Node B obtained throughthe synchronization process to the SRNC, so that the SRNC is clearlyinformed whether the Node B has the E-DPCCH capability.

For example, the DRNC can add an IE indicating whether the Node B hasthe E-DPCCH power boost capability in an Uplink Signaling TransferIndication message to notify the SRNC whether the Node B can perform thechannel estimation by using the E-DPCCH power boost characteristic.

For example, the DRNC may also add an IE indicating whether the Node Bhas the E-DPCCH power boost capability in an RL Response message tonotify the SRNC whether the Node B can use the E-DPCCH power boostcharacteristic to perform the channel estimation.

The DRNC may also forward the capability information of the Node B tothe SRNC through other interactive messages with the SRNC, and thepresent invention is not limited to the two modes described above.

Step 304: The SRNC configures the resources of the Node B for the UEaccording to the capability of the UE.

In step 303, the SRNC is clearly informed whether the Node B has theE-DPCCH power boost capability through the forwarding of the DRNC.Therefore, when configuring the resources of the Node B for the UE, theRNC configures the Node B to perform or not to perform the channelestimation by using the E-DPCCH power boost characteristic for the UEaccording to whether the UE has the E-DPCCH power boost capability. Thespecific implementation of the configuration is as described in step 203in the second embodiment of the present invention.

In this embodiment, step 301 may be performed before or after step 302,because in step 301, the DRNC acquires the capability information of theNode B, and in step 302, the SRNC acquires the capability information ofthe UE, and the two steps are completed by the DRNC and the SRNCrespectively, and have no specific correlation. Step 303 must beperformed after step 301, because the DRNC can forward the capability ofthe Node B to the SRNC only after the DRNC acquires the capability ofthe Node B. Step 303 may be performed before or after step 302, becausein step 302, the SRNC is informed of the capability of the UE, and instep 303, the DRNC forwards the capability of the Node B to the SRNC,and two steps have no specific correlation.

According to the third embodiment of the present invention, the DRNC isclearly informed whether the Node B has the E-DPCCH power boostcapability through an Audit procedure or a Resource Status Indicationprocedure, or through a combination thereof. The DRNC forwardsinformation about whether the Node B has E-DPCCH power boost capabilityto the SRNC, so that the SRNC is clearly informed whether the Node B canperform the channel estimation by using the E-DPCCH power boostcharacteristic. Accordingly, the SRNC is clearly informed whether the UEand the Node B have the E-DPCCH power boost capability. Therefore, whenthe UE and the Node B both have the E-DPCCH power boost capability, theNode B is configured to perform the channel estimation by using theE-DPCCH power boost characteristic for the UE. Therefore, the accuracyof the channel estimation of the UE under the moving scenario isimproved, and the bit error rate in high-speed data transmission underthis scenario is reduced.

Furthermore, after configuring the resources of the Node B, the RNC canfurther configure the resources of the UE, so that the resourceconfiguration of the UE is consistent with that of the Node B.

A fourth embodiment of the present invention is described in detail withreference to FIG. 4. The fourth embodiment provides a resourceconfiguration method, which includes the following steps:

Step 401: An RNC is informed of capability information of a UE.

During the process for initiating the RRC connection setup, the UEreports the complete capability information thereof to the RNC, and theRNC is clearly informed whether the UE has the E-DPCCH power boostcapability. The specific implementation is as described in step 202 inthe second embodiment of the present invention.

Step 402: The RNC configures resources of a Node B according to thecapability of the UE.

When the RNC synchronize with the Node B the capability information ofthe Node B, the Node B does not report whether it has the E-DPCCH powerboost capability, and at this time, the RNC considers that the Node Bhas the E-DPCCH power boost capability by default. Therefore, when theRNC configures the resources of the Node B for the UE according to thecapability of the UE, if the UE has the E-DPCCH power boost capability,the RNC configures the Node B to perform the channel estimation by usingthe E-DPCCH power boost characteristic for the UE.

Therefore, during the RL setup process or the RL re-configurationprocess, the RNC configures parameters related to E-DPCCH power boostfor the Node B.

Step 403: The RNC re-configures the resources of the Node B according tofeedback of the Node B.

When the Node B does not have the E-DPCCH power boost capability, theNode B returns an RL Setup Failure message to the RNC, and the RL SetupFailure message carries the reason of setup failure. If the RL setupfails because the Node B does not have the E-DPCCH power boostcapability, the failure reason returned to the RNC by the Node Bincludes the information indicating that the Node B does not have theE-DPCCH power boost capability.

After the RNC receives the failure reason returned by the Node B, theRNC is clearly informed that the Node B does not have the E-DPCCH powerboost capability, and re-initiates the RL setup and does not configurethe parameters related to E-DPCCH power boost for the Node B in thesetup request.

In this embodiment, step 403 is optional. If the Node B has the E-DPCCHpower boost capability, step 403 is not needed, because when the Node Bhas the capability, the Node B performs the channel estimation by usingthe characteristic, and does not return the RL Setup Failure messageaccordingly.

According to the fourth embodiment of the present invention, during thesynchronization process, as the Node B does not report whether it hasthe E-DPCCH power boost capability, the RNC considers that the Node Bhas the capability by default. Therefore, when the UE has the E-DPCCHpower boost capability, the RNC configures the Node B to perform thechannel estimation by using the E-DPCCH power boost characteristic forthe UE because the RNC considers that the Node B has E-DPCCH power boostcapability by default. Therefore, the quality of the channel estimationis improved, and the bit error rate in high-speed data transmission isreduced.

Furthermore, according to the fourth embodiment of the presentinvention, when the Node B does not have the E-DPCCH power boostcapability, though the RNC considers that the Node B has the capabilityby default as the Node B does not report whether it has the capabilityduring the synchronization process, the RNC still can be informed of thecapability of the Node B during the re-configuration process, so theproblem of inconsistent configuration of the Node B and the UE will notoccur.

Next, a fifth embodiment of the present invention is described in detailwith reference to FIG. 5. The fifth embodiment provides a resourceconfiguration method during movement of a UE, which includes thefollowing steps:

Step 501: An SRNC is informed of a capability of a UE, and the specificimplementation is as described in step 302 in the third embodiment ofthe present invention.

Step 502: The SRNC configures resources of a Node B for the UE accordingto the capability of the current UE.

When the Node B and the DRNC synchronize the capability information ofthe Node B, the Node B does not report whether it has the E-DPCCH powerboost capability, and the DRNC considers that the Node B has the E-DPCCHpower boost capability by default.

When the DRNC forwards the capability information of the Node B to theSRNC, it does not forward information about whether the Node B has theE-DPCCH power boost capability, and at this time, the SRNC considersthat the Node B has the E-DPCCH power boost capability by default.

Therefore, when the SRNC configures the resources of the Node B for theUE, if the UE has the E-DPCCH power boost capability, the SRNCconfigures the Node B to perform the channel estimation by using theE-DPCCH power boost characteristic for the UE. In this case, the RLSetup or RL Re-configuration message sent to the DRNC by the SRNCcarries parameters related to E-DPCCH power boost, and the RL Setup orRL Re-configuration message sent to the Node B by the DRNC also carriesthe parameters related to E-DPCCH power boost.

Step 503: The SRNC re-configures the resources of the Node B accordingto feedback of the Node B.

When the Node B does not have the E-DPCCH power boost capability, if theUE has the capability, the SRNC configures the Node B to perform thechannel estimation by using the E-DPCCH power boost characteristic forthe UE because the SRNC considers that the Node B has the capability bydefault.

At this time, as the Node B does not have the E-DPCCH power boostcapability, the Node B returns an RL Setup Failure message to the DRNC,and this message carries the failure reason indicating that the Node Bdoes not have the capability. After receiving the RL Setup Failuremessage returned by the Node B, the DRNC returns an RL Setup Failuremessage to the SRNC, which carries the failure reason indicating thatthe Node B does not have the E-DPCCH power boost capability. After theSRNC is informed that the RL setup fails because the Node B does nothave the E-DPCCH power boost capability, the SRNC re-initiates the RLsetup process or the RL re-configuration process, and does not configurethe parameters related to E-DPCCH power boost in an RL Setup Request orRL Re-configuration Request.

According to the fifth embodiment of the present invention, during thesynchronization process, as the Node B does not report whether it hasthe E-DPCCH power boost capability, the DRNC considers that the Node Bhas the capability by default, so the SRNC also considers that the NodeB has the capability by default. Therefore, when the UE has the E-DPCCHpower boost capability, the SRNC configures the Node B to perform thechannel estimation by using the E-DPCCH power boost characteristic forthe UE because the SRNC considers that the Node B has the E-DPCCH powerboost capability by default. Therefore, the quality of the channelestimation is improved, and the bit error rate in high-speed datatransmission is reduced.

Furthermore, according to the fifth embodiment of the present invention,when the Node B does not have the E-DPCCH power boost capability, duringthe synchronization process, the DRNC considers that the Node B has thecapability by default as the Node B does not report whether it has thecapability, and the SRNC also considers that the Node B has thecapability accordingly. However, according to the failure reasonreturned by the Node B, the SRNC can re-configure the resources of theNode B, so the problem of inconsistent configuration of the Node B andthe UE will not occur.

It is known from the fourth embodiment and the fifth embodiment of thepresent invention that, when the RNC of the fourth embodiment is anSRNC, it may be considered that the method of the fourth embodiment canbe used to solve the problem of resource configuration under the movingscenario in the fifth embodiment. Because the DRNC does not have thedecision-making function in the fifth embodiment and merely acts in atransfer process, the SRNC controls the capability information of the UEand the Node B ultimately, and performs resource configuration accordingto the capability information of the UE and the Node B.

Next, a sixth embodiment of the present invention is described in detailwith reference to FIG. 6. The sixth embodiment provides a resourceconfiguration method, which includes the following steps:

Step 601: An RNC acquires capability information of a UE, and thespecific implementation is as described in step 202 in the secondembodiment of the present invention.

Step 602: The RNC configures resources of a Node B for the UE accordingto a capability of the UE.

During the synchronization process of the RNC and the Node B, the Node Bdoes not report whether it has the E-DPCCH power boost capability. Inthis case, the RNC considers that the Node B has the E-DPCCH power boostcapability by default.

Therefore, when the UE has the E-DPCCH power boost capability, the RNCconfigures the Node B to perform the channel estimation by using theE-DPCCH power boost characteristic for the UE.

Step 603: The Node B performs resource configuration according to itscapability.

When the Node B does not have the E-DPCCH power boost capability, if theUE has the capability, the RNC configures parameters related to E-DPCCHpower boost for the Node B because the RNC considers that the Node B hasthe capability by default. At this time, the Node B performs the channelestimation by using the DPCCH because the Node B does not have thecapability.

The resource configuration method provided in this embodiment can alsobe used under the moving scenario. Under the moving scenario, the RNC inthis embodiment is an SRNC, and the SRNC acquires the capabilityinformation of the Node B through the forwarding of the DRNC, and wheninformation about whether the Node B has the E-DPCCH power boostcapability is not forwarded, the SRNC considers that the Node B has thecapability by default. Therefore, when the UE has the E-DPCCH powerboost capability, the SRNC configures the parameters related to E-DPCCHpower boost for the Node B. The Node B determines whether to perform thechannel estimation by using the E-DPCCH power boost characteristicaccording to the capability of the Node B.

According to the sixth embodiment, the RNC considers that the Node B hasthe E-DPCCH power boost capability by default when the Node B does notreport whether it has the capability, and when the UE has the E-DPCCHpower boost capability, the RNC configures the parameters related toE-DPCCH power boost for the Node B. Therefore, when the UE and the NodeB both have the E-DPCCH power boost capability, the RNC enables the UEand the Node B to perform the channel estimation by using thecharacteristic through the resource configuration. Thus, the accuracy ofthe channel estimation is improved, and the bit error rate in high-speeddata transmission is reduced.
